from the chamber, when "the protuberance e on the front edge oftheextractorstrikes against, the part c of the frame, which throws 'thepointof the extractor quickly backward, giving the' said extractor asudden accelerated movement backward, and ejecting the shell entirelyfrom When the extractor is thus the 'projection ftilts-over upon thespring b sldevbf the said projection, and the hammer is then moved back,as before, the extractor 'A gate, F, is pivoted at sI to the frame orside plate-in rear ot' the;cylindcrfwhich gate is provided with a planeprojection, o, which,

Instead-of being .pivoted'tohthe hammer, pivoted tonother piece,

I), said piece having a recess, t', which engages with a pin, inthe-.hammer. In this case the spring'b maybe arranged on the. frame,inside, or on theA side plate, but in the same shown in dotted lines inFig. IV, so that what'- ever the extractor is 'attached or pivotedto,

as it vibrates back and forward, itis movements and operations areprecisely alike.

It willbe seen that when the hammer is at riesameI half-cock the'ejector isbeldin a position tltv ed back by the'slning, so that thepoint ofthe ejector is ou't ot' the way when loading the arm, and isheld-in a position tilted forward,

ready for extracting the shell whenthe hammer is at 'full cock, theextractor being tilted "or thrown forward bycontact with the projccl.
